POLYESTER CHIPS - BOTTLE GRADE CHIPS

PET (PolyEthylene Terephthalate) is a strong but lightweight form of clear polyester. It is used to make containers for soft drinks, juices, alcoholic drinks, water, edible oils, household cleaners, and other food and non-food applications. Being a polymer, polyethylene terephthalate's molecules consist of long chains of repeating units containing the carbon, oxygen and hydrogen organic elements only.

After PET raw material is formed, it is then used for producing PET bottles. Making a PET bottle starts from the raw material: ethylene and paraxylene. These two substances' derivatives (ethylene glycol and terephthalic acid) get into reaction to obtain the PET resin. The resin, in the shape of small cylinders called pellets, is melted and injected into a mould to make a preform. The preform, a sort of test tube shorter than what the bottle will be but with thicker walls, is then blow-moulded. During the blow-moulding phase, high-pressure air is blown into the preform allowing it to take the exact shape of the mould it is set into. The final product is a transparent, strong and lightweight bottle.
